Skin Deep (1989)

Hard-drinking novelist Zach Hutton (John Ritter) spirals out of control after his wife (Alyson Reed) and mistress both leave him. Alone and crippled by a bad case of writer's block, Zach slips in and out of casual relationships and one-night stands, while his drinking becomes more and more severe.

With the help of a bartender (Vincent Gardenia) and his therapist (Michael Kidd), Zach confronts his demons -- women and alcohol -- and rediscovers his writing voice.
